Waveshare Round-Shaped All-In-One Capacitive Fingerprint Sensor (G)

20,95 €

Description

The Waveshare UART Fingerprint Sensor (G) is a compact, round capacitive fingerprint sensor with a Cortex-based controller and an integrated matching algorithm. This fingerprint sensor accepts UART TTL commands for enrollment, image capture, template extraction and comparison, so a host does not need to implement the recognition algorithm.

The 508 DPI capture window, touch wake-up output and LED indicator make the fingerprint sensor suitable for embedded identification projects. It stores up to 1000 fingerprint templates; the stated matching time is less than 0.5 seconds when searching no more than 500 templates.

Notice: For PC connection, a USB-to-UART serial module such as the FT232 must be provided by the user.

Features

  • Integrated sensor, processor and fingerprint algorithm simplify UART-based development.
  • Capacitive fingerprint sensor with 508 DPI resolution and a 192 × 192 pixel image array.
  • Up to 1000 stored templates; enrollment, matching, image capture and template transfer are supported.
  • Touch detection provides a wake-up signal, while the illuminated capture window indicates status.
  • It can interface with suitable STM32 or Raspberry Pi hosts through UART TTL.

FAQ

How many fingerprints can this fingerprint sensor store?

It supports up to 1000 fingerprint templates. The specified comparison time of less than 0.5 seconds applies to a search set of up to 500 templates.

Does this module have USB?

No. This G version exposes UART TTL; a separate USB-to-UART adapter is needed when connecting it to a PC.

How does touch wake-up work?

When a finger touches the window, the IRQ/WAKEUP output goes high. Consult the pinout and 3.3 V supply requirements before wiring.
